  • Ep 0 164 709 A2 discloses a process for laying several plies onto the outer circumference of a building drum.
  • the Applicant observed that the quality of the tyres produced seems to depend, among a plurality of factors, also from the correct winding of continuous elongated elements on the forming drum. Such correct winding would allow guaranteeing the mutual joining of the opposite ends of the continuous elongated element cut to size and the uniformity of the geometric and physical characteristics of the element itself along the circumferential extension of the forming drum.
  • the Applicant perceived that the aforementioned uniformity is particularly influenced by the longitudinal stresses (tension or compression) to which the continuous elongated element is subjected during the deposition on the forming drum.
  • the Applicant felt the need of controlling, during the deposition on the drum and the winding, the longitudinal deformation of the continuous elongated element, preferably cut to size, at each transverse section so that it is deposited to guarantee the correct joining and geometric uniformity.
  • the Applicant found that providing the winding of the continuous elongated element on a forming drum, controlling - during the winding - the advancing speed of a transport surface which supports it towards the forming drum and the linear speed of the radially external surface of said forming drum, allows obtaining the desired uniformity for the substantial control of the tension or compression longitudinal stresses during the winding.
  • the length of the continuous elongated element cut to size can be adjusted so that the opposite ends perfectly match along the entire axial extension thereof (i.e. along the entire width of the continuous elongated element) and/or in such a manner as to confer to the continuous elongated element cut to size and wound a possible longitudinal tension/compression required for the component of the tyre being formed.

  • the second face advances together with the radially external surface with a relative null speed with respect to said radially external surface.
  • the Applicant deems that, controlling and adjusting the speed of the aforementioned surfaces (transport surfaces and radially external with respect to the drum), allows conferring, to each stretch of the section, axial deformations that are summed and/or subtracted from the deformation due to the curvature of the section that is wound on the forming drum, in such a manner to obtain a lengthening or shortening of the entire section in its entirety.
  • the Applicant deems that the support surface continues up to the forming drum (without free stretches along which the section remains suspended), it allows maintaining said section guided and guarantee the correct centring/positioning on the drum.

  • Such values are sufficient to correct the length errors caused by the variability of the step of cutting and/or stretching (stretch) or contraction (upsetting) the section so that the continuous elongated element wound on the drum has predetermined tension/contraction characteristics.
  • the process comprises: fastening a theoretical length of the section equal to the circumferential extension of the radially external surface to the forming drum; measuring the true length of the section before winding it around the forming drum; setting said ratio to bring the section wound on the forming drum to the theoretical length. Controlling the length and adjustment of the same occurs after cutting and during the winding on the drum.
